THIS IS ANECDOTAL EVIDENCE, and MAY BE COINCEDENTAL: I was having serious problems using Uber because both forms of payment I was using were failing processing. They were both credit cards I had used earlier in the night, and were both certainly valid. I became frustrated, and as Uber has no customer support I had to sort out contingency. I downloaded lyft and then Uber started to work. It processed both cards and let me request a a car (if it does not process it saves the info but does not let you request). So instantly, without me doing anything, I was immeadiately able to use Uber after I downloaded lyft, without doing anything extra. So I now exclusively use Lyft. It has been cheaper for all comparable distances I can track.
